Practical work.
A wider perspective.

I am an Electrical and Electronics Engineering student at B.S.A. Crescent Institute of Science and Technology. My work includes ESP32 interfacing, inductive power transfer and a fingerprint attendance workflow. Alongside engineering, I serve as Joint Secretary of Crescent Energy Club and have coordinated the 17 Frames event.

Wireless Power Transfer with Smart Monitoring

Batch lead · Four-member team
2026 — present

An inductive power-transfer prototype connecting coil design, receiver conditioning and embedded monitoring.

Led the transmitter and receiver development using coupled coils, a bridge rectifier and capacitor filtering. Rewinding the receiver coil to 25 turns produced a measured 5 V DC output.

The monitoring extension covers ESP32 voltage, current and temperature sensing with a Wi-Fi interface.

Smart Fingerprint Attendance System

Embedded hardware & application integration
November — December 2025

A biometric attendance workflow combining a fingerprint sensor, local status display and database logging.

Interfaced the R307S module with ESP32 and confirmed sensor communication over UART. Worked on an SSD1306 OLED interface and attendance records through a XAMPP, PHP and MySQL backend.

Engineering work included wiring checks, serial troubleshooting, Wi-Fi connectivity and local server/database setup.
